Frost? Frost?

Long gone are the stories about tent zips freezing so hard the zip wouldn't open.
I can remember thick ice inside my car in the morning.

That was before the date moved from 3rd Fri (which can be quite late) to 2nd w/e.

And before global warming; which if you looked at a graph of temp v days it would show a shallow fall, and a small change in temp moves the frost point a long way. We are talking averages but the first year I saw Bromyard dust lit by the sunshine I knew global warming was telling us something incontrovertable.

But I now have 4 sleeping bags (double inside double) & a caravan - am I becoming a wimp in my dotage?
